<p>Portmarnock is a wonderful long beach on the Northside of Dublin. It is the sea side&nbsp;of a sand spit where&nbsp;the Portmarnock Championship golf&nbsp;course sits.</p>

<p>There is a long strand perfect for refreshing walks with wonderful views across the water towards Howth, Ireland&#39;s Eye and Lambay Island.</p>

<p>It is very popular with families during the summer and dog walkers all year around.</p>

<p>The sand is nice and soft - perfect for sand castles.</p>

<p>Lifeguards are on duty during the summer months and you are advised to swim between the flags.&nbsp;</p>
